Description

Technical Field

[0001] This utility model relates to the field of silencer production technology, and in particular to a pretreatment clamping device for welding boiler silencer plates. Background Technology

[0002] The perforated plate of the boiler tail-end silencer is the core noise reduction component. By adopting small-hole injection silencing technology, the high-frequency noise of high-speed airflow is converted into ultrasonic noise through a porous structure. At the same time, the impedance composite structure is used to further reduce mid- and low-frequency noise, thus achieving wide-band silencing.

[0003] The muffler's outer shell is made of steel plates rolled into a cylindrical shape and then welded. However, the steel plates are quite thick, resulting in a protruding weld seam after welding. Thicker steel plates are also prone to incomplete welds. Therefore, a bevel needs to be made at the weld seam during welding. The existing method is to grind the connection area using grinding equipment. However, long-distance grinding not only fails to guarantee the quality of the bevel but also consumes a lot of time. Machining with a planer can quickly solve the above problems. To ensure the quality of the bevel machining, the steel plate needs to be effectively clamped. Existing clamping equipment cannot guarantee the machining angle, cannot adjust the support position according to the length of the plate, and is difficult to remove once the plate is in contact with the clamping equipment. Utility Model Content

[0004] This utility model addresses the deficiencies in the existing technology by providing a pretreatment clamping device for welding boiler silencer plates.

[0005] This utility model is achieved through the following technical solution: A pretreatment clamping device for welding boiler silencer plates includes a fixed base, a hydraulic cylinder installed at one end of the fixed base, a support mechanism clamped on the top of the fixed base, a clamping mechanism and a holding mechanism installed on the top of the support mechanism. The top of the fixed base has a sliding groove, and the bottom of the support mechanism is clamped in the sliding groove at the top of the fixed base. The support mechanism includes a sliding plate, a support rod, a connecting plate, a backing plate and a limiting strip. The support rod is fixedly installed on the upper surface of the sliding plate, the connecting plate is fixedly installed on the top of one end of the sliding plate, the backing plate is fixedly installed on the top of the support rod, and the limiting strip is fixedly installed on the top end of the backing plate. The clamping mechanism includes an adjusting base, a connecting frame, a pressure knob, a screw, an outer sleeve seat and a pressure plate. The connecting frame is fixedly installed on the outside of the adjusting base, the pressure knob is threadedly connected to the connecting frame, the pressure knob is fixedly installed on the bottom inside the adjusting base, and the pressure plate is fixedly installed on the outside of the outer sleeve seat.

[0006] In a preferred embodiment of this utility model, the clamping mechanism includes a card seat, a wedge-shaped slider, a pressure rod, a guide rod, a spring, and a fixing rod. The card seat has a slot on its inner top side, the wedge-shaped slider is engaged in the slot on the inner top side of the card seat, the pressure rod is fixedly disposed on the top of the wedge-shaped slider, the guide rod is fixedly disposed in the slot on the top of the card seat, the spring is sleeved on the outside of the guide rod, and the fixing rod is fixedly disposed on the top of the card seat. The clamping mechanism is mainly used after the end of the plate is processed to make it easy to clamp the edge of the plate, thereby quickly pulling the plate that is in contact with the backing plate away.

[0007] In a preferred embodiment of the present invention, the top of the outer side of the back plate is provided with a slot that mates with the bottom of the card seat, the top of the pressure rod passes through and extends to the top outer side of the card seat, and the top of the card seat is provided with an oblong hole that mates with the pressure rod. The slot at the top of the plate facilitates the insertion of the clamping mechanism to clamp the edge of the plate.

[0008] In a preferred embodiment of the present invention, the backing plate is inclined at 45°, and a groove is provided on the surface of the backing plate to cooperate with the outer sleeve seat. One side of the pressure plate is attached to the bottom of the backing plate. The angle of the plate determines the clamping angle of the plate, so that after the planer is processed, a 45° bevel is opened at the end of the plate.

[0009] In a preferred embodiment of the present invention, a locking block is provided at the bottom of the adjusting seat, a screw is fixedly disposed at the bottom of the locking block, an outer sleeve is sleeved on the outside of the locking block at the bottom of the adjusting seat, and one end of the screw passes through and extends to the outside of one side of the pressure plate; Tightening the nut on the screw surface changes the distance between the back locking block of the adjusting seat and the inner outer seat, thereby clamping the pressure plate and the adjusting seat together and fixing the clamping mechanism.

[0010] The beneficial effects of this utility model are: The pre-treatment clamping equipment for welding boiler silencer plates adjusts the position of the clamping mechanism according to the length of the plate, so that the plate extends to the outer side of the top of the plate to a suitable length, which facilitates rapid processing by the planer.

[0014] like Figure 1-4 The pretreatment clamping device for welding boiler silencer plates shown includes a fixed base 1, a hydraulic cylinder 2 installed at one end of the fixed base 1, a support mechanism 3 clamped on the top of the fixed base 1, a clamping mechanism 4 installed on the top of the support mechanism 3, and a holding mechanism 5. A sliding groove is provided on the top of the fixed base 1, and the bottom of the support mechanism 3 is clamped within the sliding groove on the top of the fixed base 1. The support mechanism 3 includes a sliding plate 31, a support rod 32, a connecting plate 33, a backing plate 34, and a limiting strip 35. The support rod 32 is fixedly mounted on the upper surface of the sliding plate 31. The connecting plate 33 is fixedly installed at the top of one end of the sliding plate 31, the backing plate 34 is fixedly installed at the top of the support rod 32, and the limiting strip 35 is fixedly installed at the top end of the backing plate 34. The clamping mechanism 4 includes an adjusting seat 41, a connecting frame 42, a pressure knob 43, a screw 44, an outer sleeve seat 45, and a pressure plate 46. The connecting frame 42 is fixedly installed on the outside of the adjusting seat 41, and the pressure knob 43 is threadedly connected to the connecting frame 42. The pressure knob 43 is fixedly installed at the bottom of the inner side of the adjusting seat 41, and the pressure plate 46 is fixedly installed on the outside of the outer sleeve seat 45.

[0015] Specifically, the clamping mechanism 5 includes a clamping seat 51, a wedge-shaped slider 52, a pressure rod 53, a guide rod 54, a spring 55, and a fixing rod 56. A groove is formed on the inner side of the top of the clamping seat 51, the wedge-shaped slider 52 is clamped in the groove on the inner side of the top of the clamping seat 51, the pressure rod 53 is fixedly mounted on the top of the wedge-shaped slider 52, the guide rod 54 is fixedly mounted in the groove on the top of the clamping seat 51, the spring 55 is sleeved on the outside of the guide rod 54, and the fixing rod 56 is fixedly mounted on the top of the clamping seat 51. A groove is formed on the top of the outer side of the backing plate 34 that connects to the bottom of the clamping seat 51. The slots are designed to fit together. The top of the pressure rod 53 passes through and extends to the outer side of the top of the card seat 51. The top of the card seat 51 has an oblong hole that fits with the pressure rod 53. The back plate 34 is inclined at 45°. The surface of the back plate 34 has a sliding groove that fits with the outer sleeve 45. One side of the pressure plate 46 is attached to the bottom of the back plate 34. The bottom of the adjusting seat 41 is provided with a locking block. The screw 44 is fixedly set at the bottom of the locking block. The outer sleeve 45 is fitted outside the locking block at the bottom of the adjusting seat 41. One end of the screw 44 passes through and extends to the outer side of one side of the pressure plate 46.

[0016] In this embodiment, the height of the clamping mechanism 4 is first adjusted according to the length of the plate. After loosening the nut on the surface of the screw 44, the outer sleeve 45 can slide in the groove on the surface of the backing plate 34 to adjust the height of the clamping mechanism 4. Then, the nut is tightened so that the pressure plate 46 and the adjusting seat 41 clamp the backing plate 34 to achieve effective fixation. After the plate is opened to the inside of the connecting frame 42, one side of the plate is attached to the backing plate 34, and one end of the plate is opened in the inner groove of the limiting strip 35. Then, the pressure knob 43 is tightened to effectively fix the plate.

[0017] Furthermore, the telescopic end of the hydraulic cylinder 2 is fixed to the outside of the connecting plate 33. The telescopic movement of the hydraulic cylinder 2 allows the support mechanism 3 to slide within the top groove of the fixed seat 1, thus positioning the top of the plate at the bottom of the planer cutter. This allows for plate position adjustment after clamping, and the planer cutter moves back and forth. A 45° bevel is created at the end of the plate according to the tilt angle of the backing plate 34, and the plate is then rotated for processing at both ends. After the plate is rolled, a 90° bevel is created at the welding position, facilitating welding and effectively improving welding quality. After the plate is in contact with the backing plate 34... If the plate is difficult to remove, the clamping mechanism 5 can be used to operate it. The bottom of the card holder 51 is locked into the corresponding slot on the surface of the backing plate 34. Push it forward until the card holder 51 is locked onto one end of the plate. Then, hold the pressure rod 53 and the fixing rod 56 and apply pressure to make the pressure rod 53 move towards the fixing rod 56. This causes the wedge slider 52 to move forward, and the spring 55 to be compressed and contracted. After the wedge slider 52 moves forward, its bottom slope will lock onto the end of the plate, thus clamping the plate. At this time, releasing the pressure knob 43 will make it easy to pull the plate away from the surface of the backing plate 34, which is convenient for the plate disassembly work.
